这个rspec测试有什么问题

Question

I have a helper class in rails that has a method like this:

def doSomething(name, *args)
 result = ""
 args.each do |arg|
  if (name == 'something')
   result += arg
  end
 end 
 result
end

My rspec method to test is like this:

it "Should return a hex array for normal input" do
  expect(helper.doSomething("somename", 1, 2,3, 4,5)).to eq("")
end

When I run the rspec I run into the following error:

ArgumentError: wrong number of arguments(1 for 0)

What am I doing wrong here? Any help is appreciated.

EDIT::::

Sorry folks this is not the complete code. I tried to create something similar but in correcting my previous code I discovered the error in some other part.

Answer 1

It would be great if you could include the stack trace from the error as well. Your test looks correct except for the fact that you are trying to add fixnums to a string at result += arg , which will result in an implicit conversion error.

I'd say fix that first, and if the problem still exists, please post additional information.

Answer 2

I think you're missing array syntax in your rspec method.

Right now your doSomething method has 6 arguments in rspec when it should have 2 arguments(which it does when you establish it in your helper). Try to refactor this part of your rspec test ("somename", 1, 2,3, 4,5) *The numbers should be in array syntax.
